Hide group based on length of member parts

GoJS

Hi

is it possible to bind the member parts length to group visibility, and hide groups that have no members?

You won’t be able to use a binding, but you can set Group.memberAdded and Group.memberRemoved functions to handle the visibility.

Add this to your group template:

{
  visible: false,
  memberAdded: function(grp, part) {
    grp.visible = true;
  },
  memberRemoved: function(grp, part) {
    if (grp.memberParts.count <= 0) grp.visible = false;
  }
}

Example, notice Beta is not visible:
